Answer:
x = 4,
x = -2
Step-by-step explanation:
( x - 4 ) ( x + 2 ) = 0
Find out when the equation is 0,
When x = 4,
substitute in 4 for x,
( 4 - 4 ) ( 4 + 2 ) = 0
(0) ( 6) = 0 (any number multiplied by 0 is 0).
When x = -2
Substitue in -2 for x,
( -2 - 4 ) ( -2 + 2 ) = 0
(-6) (0) = 0 (again, any number multiplied by 0 is 0).
Answer:
the answer should be -1 to 3
Step-by-step explanation:
or it could take another form -3> 4
To find the mean: You have to add them all together, then divide them by how many numbers there are.
So: 23+25+32+35+36+25+27 = 203
How many numbers did we add up? 7.
203 ÷ 7 = 32.85714 (That is the mean rounded up to the nearest hundredth thousandth).
Answer:
the formula for finding the perimeter of a rectangle is P=2L+2W
an example of how to find the perimeter is
Explanation:
For a rectangle, its perimeter is the sum of all for sides.
The rectangle has a perimeter of 54. Find the lengths of the unknown side. That is, find S.
54=20+20+S+S
Simplify
54=40+2S
Solve for S
14=2S
S=7
Step-by-step explanation:
